- regions read their lines through TextMerge's accessors; conflicts and resolve
split with similar's tokenize_lines, so a lone return ends a line everywhere
- the merged ending and line breaks know a lone return
- taking both sides separates them only when both hold text
- merge views split rows the same way
- merges keep each line's ending and the last newline; resolve keeps every other byte
- the split view numbers each side from its own file
- hunk headers come from similar's UnifiedHunkHeader: an empty side starts before its range
- the commit subject counter sits in the input's suffix
- clipped code rows in diffs, merges, blame and review set their line height
- gallery: scripted split view and a long subject
